Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the KT11B0SAM35LFG is determined by strict equivalence across the following critical parameters:

• Circuit Configuration: SPST-NO topology must be maintained
• Contact Rating: 1VA @ 32VAC/DC electrical specification
• Mounting Type: Surface Mount, Right Angle configuration
• Actuator Orientation: Side Actuated design
• Termination Style: Gull Wing leads
• Physical Outline: 7.57mm x 4.38mm footprint
• Operating Force: 300gf actuation force
• Ingress Protection: IP57 sealed construction
• Operating Temperature: -40°C ~ 90°C range
• Mechanical Life: 100,000 Cycles minimum

The KT11B0SAM34LFS meets all these criteria and is classified as a direct substitute. The primary distinction is packaging format and product status, with the substitute part available in active production.

Parameter Comparison

Engineering Selection Recommendations

The KT11B0SAM34LFS is the direct substitute for the obsolete KT11B0SAM35LFG. Both components share identical electrical and mechanical specifications, ensuring functional equivalence in circuit applications.

Product Status Consideration: The main part is obsolete, while the substitute is in active production. This status difference makes the KT11B0SAM34LFS the appropriate selection for new designs and ongoing procurement.

Compliance Alignment: Both parts maintain REACH Unaffected status and EAR99 classification. The substitute part carries ROHS3 Compliant certification, representing current regulatory compliance standards, compared to the main part's RoHS Compliant designation.

Packaging Difference: The substitute is supplied in Tape & Reel format, which is standard for production environments and automated assembly processes. The main part was supplied in bulk packaging. This packaging difference does not affect electrical or mechanical performance.

Frequently Asked Questions (FAQ)

Q: Can KT11B0SAM34LFS be used as a direct replacement for KT11B0SAM35LFG?

A: Yes. Both parts are electrically and mechanically identical. They share the same circuit configuration (SPST-NO), contact rating (1VA @ 32VAC/DC), mounting type (Surface Mount, Right Angle), actuator specifications, and sealed construction (IP57). The substitute is the recommended choice due to active production status.

Q: What is the difference between these two part numbers?

A: The primary differences are product status and packaging format. KT11B0SAM35LFG is obsolete and supplied in bulk packaging. KT11B0SAM34LFS is in active production and supplied in Tape & Reel format. The RoHS certification level also differs (RoHS Compliant vs. ROHS3 Compliant), reflecting current regulatory standards.

Q: Are the physical dimensions identical?

A: Yes. Both parts have identical outline dimensions of 7.57mm x 4.38mm and use the same Gull Wing termination style, ensuring PCB footprint compatibility.

Q: Do these parts have the same operating specifications?

A: Yes. Operating force (300gf), mechanical life (100,000 cycles), operating temperature range (-40°C ~ 90°C), and ingress protection rating (IP57) are identical across both parts.

Q: Is Tape & Reel packaging compatible with my assembly process?

A: Tape & Reel packaging is standard for automated surface mount assembly. If your process requires bulk packaging, contact your supplier regarding alternative packaging options for the KT11B0SAM34LFS.
